Configure filters to include or exclude data and events

After you configure the monitor types in the PATROL Agents, they send the collected data and the generated events to the Infrastructure Management server. You can configure filters to control the data and events that are sent to the Infrastructure Management server per parameter. 

You can filter the data either from a specific Agent or from a specific monitor type. The supported filtering options are as follows:

• Send events only
• Send trended performance data only
• Send trended performance data and events
• Send no trended performance data and no events

Configure polling intervals

Specify the time interval between two consecutive data polls. You need to specify a separate poll interval for every parameter. 

1. Click the Polling Intervals tab. 
2. Add a polling interval:
   1. Click Add Polling Interval.

   2. Select values for the following options:

      - Monitoring Solution  - Version - Monitor Type - Parameter - Parameter Polling Interval

   3. Click OK. The polling interval is added to the table in the Polling Interval page.
3. To add more polling intervals, repeat the previous step. 
4. To modify the properties of a polling interval: Click the action menu associated with that polling interval, and select Edit.
5. To delete a polling interval: Click the action menu associated with that polling interval and select Delete.

Define thresholds on PATROL Agents

Configure range-based thresholds for attributes of a monitor type on the PATROL Agents. You can specify whether the thresholds apply to a monitor type or to an instance of a monitor type.

1. Click the Agent Threshold tab.

2. Click Add Agent Threshold.  

   The [confluence_table-plus] macro is a standalone macro and it cannot be used inline.
   
   

3. Click OK. The threshold is added to the table on the Agent Threshold page.

Create server-level thresholds

You can create thresholds for the monitor instances on the Infrastructure Management server. For information about the types of thresholds, see Thresholds, KPIs, and baselines.

 
To configure the server thresholds:

1. Click the Server Threshold tab.
2. Click Add Server Threshold.    

3. Specify values for the following properties:
   

   The [confluence_table-plus] macro is a standalone macro and it cannot be used inline.
   
   

4. Click OK.  
5. To modify parameters of a threshold, click the action menu for that threshold and select Edit.
6. To remove a threshold, click the action menu for that threshold and select Delete. After you save the policy, the deleted threshold configurations are removed from the selected PATROL Agents.
   After you save or update a policy, the new threshold configurations are pushed to the selected PATROL Agents.

Define and manage configuration variables

You can define individual configuration variables or import them from a ruleset file (.cfg).

The PATROL Agent configuration is saved in a set of configuration variables that are stored in the Agent's configuration database. You can control the PATROL Agent configuration by changing the values of these configuration variables. Also, you can define a configuration variable, and the definitions are set on PATROL Agent when the policy is applied.

• To import existing configuration variables
• To add new configuration variables

To import existing configuration variables

1. In the Configuration Variable page, click the common action menu in the table and select Import.
   
2. Browse for and select the configuration file (.cfg) to be imported.
3. Click Open. The variables from the file are added to the table.

To add new configuration variables

1. Click Add Configuration Variable.

2. In the Add Configuration Variable dialog box, specify values for the following properties and click OK:

   Property	Description
   Variable	Name for the configuration variable. Important: The variable names are case sensitive and must start with slash (/). You must enter the complete path for the variable, not just the name. If the intermediate variables do not exist, the variables are created.
   Operation	Operation that you want to perform on the configuration variable. The supported operations are as follows: REPLACE: Replaces the current value of the variable on the PATROL Agent if the variable already exists. Otherwise, a new variable is created with the specified value. DELVAR: Deletes the variable from the PATROL Agent. DELETE: Deletes the value of the variable, and the variable remains empty.
   Value	Value that you want to configure for the variable and click OK. The configuration variable is added as a new row in the Configuration Variables table.

3. To add another configuration variable, repeat the earlier steps.

   
   Important: For the defaultAccount configuration variable, specify the value in the userName/password format. Note that the password can be a plain text or a PATROL Agent-encrypted string.
   Examples:

   patrol/patAdm1n
   patrol/FA4E70ECEAE09E75A744B52D2593C19F

   For the SecureStore configuration variable, specify the value in the context/data format. Note that the context and data can be a plain text or a PATROL Agent-encrypted string.
   

   Examples:

   MY_KM1;MY_KM2;MY_KM3/mysecretdata

   “EDC10278901F8CB04CF927C82828595B62D25EC355D0AF38589CE4235A246F8C63F24575073E4ECD”

   where “EDC10278901F8CB04CF927C82828595B62D25EC355D0AF38589CE4235A246F8C63F24575073E4ECD” is the encrypted form of "MY_KM1;MY_KM2;MY_KM3/mysecretdata"

4. To modify any value in a variable, click the action menu for the variable and select Edit.
   
   In the Edit Configuration Variable dialog box,  modify the properties and click OK.
5. To remove a variable, click the action menu for the variable and select Delete.
